Description

Technical Field

[0002] Road and bridge engineering is a general term for road engineering and bridge engineering. Therefore, to a certain extent, roads and bridges were born at the same time. In road and bridge construction, in order to meet construction requirements and achieve construction accuracy, it is often necessary to measure the horizontal distance between the bridge piers and the road surface, which requires the use of a level measuring instrument.

DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 6 A measuring device for road and bridge construction includes a measuring mechanism 1 and an adjusting mechanism 2 arranged below the measuring mechanism 1, a moving mechanism 3 is connected to the bottom of the adjusting mechanism 2, and the measuring mechanism 1 includes a level measuring instrument 101:

[0025] Furthermore, the adjustment mechanism 2 includes a lifting plate 201, which is located below the level measuring instrument 101. A horizontal threaded rod 203 is rotatably connected to the top of the lifting plate 201. A first motor 204 is fixedly connected to one end of the horizontal threaded rod 203. The first motor 204 is fixedly arranged on the top of the lifting plate 201. A threaded sleeve 205 is threadedly connected to the surface of the horizontal threaded rod 203. The top of the threaded sleeve 205 is connected to the level measuring instrument 101. A lifting threaded rod 206 is threadedly connected to the inner wall of the front side of the lifting plate 201. The bottom of the lifting threaded rod 206 extends to the bottom of the moving mechanism 3 and is rotatably connected thereto.

[0026] Through the cooperation of the horizontal threaded rod 203 and the first motor 204, the present device can realize the precise adjustment of the level measuring instrument 101 in the horizontal direction. The threaded connection between the threaded sleeve 205 and the horizontal threaded rod 203 provides a stable fine-tuning capability, so that the operator can make subtle adjustments to the position of the level measuring instrument 101 to ensure the accuracy of the measurement. The combination of the lifting threaded rod 206 on the front side of the lifting plate 201 and the moving mechanism 3 not only allows the level measuring instrument 101 to be adjusted in the vertical direction, but also can be moved in the horizontal plane, which greatly improves the adaptability and flexibility of the equipment in complex construction environments. The present device overcomes the problems of inconvenient adjustment and limited accuracy encountered by traditional measuring tools in complex construction sites. Through the integrated lifting and moving mechanism 3, it realizes the rapid and precise positioning of the measuring instrument in three-dimensional space, and is an effective tool for improving the efficiency and quality of road and bridge construction measurement.

[0027] Furthermore, a first mounting plate 102 is fixedly connected to one side of the level measuring instrument 101, a first electric push rod 103 is rotatably connected to one side of the first mounting plate 102, one end of the first electric push rod 103 is rotatably connected to a second mounting plate 104, and the bottom of the second mounting plate 104 is fixedly connected to the top of the threaded sleeve 205.

[0028] The introduction of the first electric push rod 103 enables the level measuring instrument 101 to not only adjust the height up and down, but also actively extend and retract in the horizontal direction, thereby achieving a more comprehensive position adjustment in a two-dimensional plane, which is very beneficial for situations that require precise alignment on a horizontal plane or operation in a limited space.

[0029] Furthermore, a second electric push rod 105 is fixedly connected to the top of the second mounting plate 104 , and a telescopic end of the second electric push rod 105 is rotatably connected to the front and rear sides of the surface of the first electric push rod 103 .

[0030] Through the coordinated work of the first electric push rod 103 and the second electric push rod 105, the level measuring instrument 101 can cope with more complex and changeable construction environments, and can provide sufficient adjustment freedom whether it is to align with a specific measuring point or to perform precise measurement in a confined space.

[0031] Furthermore, a limiting groove 202 is provided on the top of the lifting plate 201 , and the limiting groove 202 is slidably connected to the threaded sleeve 205 .

[0032] By limiting the left and right sliding range of the threaded sleeve 205 through the limit groove 202, it can be ensured that the level measuring instrument 101 works within a predetermined horizontal range, which helps construction personnel to quickly locate the effective measurement range during operation and avoid invalid or erroneous adjustment operations.

[0033] Furthermore, the moving mechanism 3 includes a moving seat 301, which is arranged below the lifting plate 201. A second motor 207 is fixedly connected to the bottom of the moving seat 301, and a lifting threaded rod 206 is fixedly connected to the output end of the second motor 207. A limiting rod 208 is fixedly connected to the rear side of the top of the moving seat 301, and the limiting rod 208 is slidably connected to the lifting plate 201.

[0034] The lifting threaded rod 206 driven by the second motor 207 allows the lifting plate 201 to move precisely in the vertical direction. Combined with the previous adjustment mechanism 2, it realizes the all-round precise positioning of the level measuring instrument 101 in three-dimensional space. The sliding connection between the limit rod 208 on the top rear side of the moving seat 301 and the lifting plate 201 sets a physical limit on the moving range to prevent equipment damage caused by excessive movement, thereby increasing safety and reliability.

[0035] Furthermore, a buffer 209 is rotatably connected to one side of the bottom of the lifting plate 201, a movable sleeve 210 is rotatably connected to the bottom of the buffer 209, a cross bar 211 is slidably connected to the inner wall of the movable sleeve 210, the cross bar 211 is fixedly arranged on the top of the movable seat 301, and a second spring 212 is movably sleeved on the surface of the cross bar 211 and fixedly connected to the movable sleeve 210 and the cross bar 211.

[0036] Furthermore, the buffer member 209 includes a buffer rod 2090, which is rotatably connected to the bottom of the movable sleeve 210, a positioning sleeve 2091 is slidably connected to the surface of the buffer rod 2090, the positioning sleeve 2091 is rotatably connected to the top of the movable sleeve 210, and a first spring 2092 is fixedly connected between the buffer rod 2090 and the positioning sleeve 2091.

[0037] The buffer member 209 includes a buffer rod 2090, a positioning sleeve 2091, a first spring 2092 and a movable sleeve 210, a cross bar 211, and a second spring 212, forming a complex buffer system. When the moving mechanism 3 encounters an external force impact or needs to slow down and stop during movement, this buffer system can effectively absorb the impact energy, reduce vibration, and improve the smoothness of operation.

[0038] Furthermore, a push handle 302 is fixedly connected to one side of the top of the moving base 301 , and a brake wheel 303 is rotatably connected to the bottom of the moving base 301 .

[0039] Through the push handle 302, the operator can easily push the entire measuring device to move on the ground, especially when the measuring position needs to be changed at the construction site. The design of the push handle 302 makes transportation more labor-saving and convenient, thereby improving work efficiency. The brake wheel 303 can be locked when necessary to prevent the device from sliding on a slope or accidentally moving when it is not needed, thereby ensuring the stability and safety of the measuring operation.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
